We compared our method with standard resizing methods based on various interpolation schemes, namely nearest neighbors, bilinear, bicubic and Lanczos. In addition to these baselines, we compared with three methods [1]}, [2]}, [3]} that focused on 2D SISR and one method [4]} that focused on 3D SISR. We note that You et al. [2]} did not report results on NAMIC. Nonetheless, You et al. [2]} were kind to provide access to their source code. We thus applied their method on both CH and NAMIC data sets, keeping the same settings and hyperparameters as recommended by the authors. As You et al. [2]}, we employed their method only on 2D super-resolution for the \(2\times \)  upscaling factor. For the other three baselines, we included the NAMIC scores reported in the respective articles [1]}, [4]}, [3]}.
